A level photography theme ideals?

Iv just finished my first year of photography and now my teacher is wanting us to pick any other theme to work on through the summer right up to January (60% of our final grade) I want to look at different places as this year I'm going on holiday, and I can travel around the UK, as well as different foods, people, culture etc but I always want to look at normal landscapes and incorporate some reflection into it but I don't know what the overall name of the theme could be, any one have any ideas? Or any other themes that I could explore would be a great help! :smile:
